From: Christophe JAILLET Date: Sat, 25 Jun 2022 12:56:05 +0000 (+0200) Subject: memstick/ms_block: Use the bitmap API when applicable X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=aabf199c4eff56e8b36a4c2807c041d93b20c1e1;p=linux.git memstick/ms_block: Use the bitmap API when applicable Use bitmap_equal() instead of hand writing it. It improves semantic and avoids some explicit computation to convert a number of bits to a number of bytes.
